I would like to pass List<SelectListItem> (not selected item but the whole "List" object) back to controller.
for example in my GET controller i would have this
ViewData["list"] = some select list from repository;
then on post I would like to get the list back from view..pretty much i'm trying to use ViewData["list"] as storage..this way I would use ajax to remove or add items to/from the list.
I need to pass a list of Entity Objects from Controller to View but not put it in the Model context. It is the users homepage, but I am putting a list of alerts on the users home page(somewhat like facebook). So I need the User Context as the Model I pass but need to pass the Alert model as well so I can show the list of alerts.. How would I do that? The code below is what I have so far..
UserController
[Code]....
UserRepository

I have a form that I don't want to post back so I need to get the form values into my controller via jquery's ajax method.Here is my test controller method:
[Code]....
When I debug the controller method and look at the lineItems parameter, it always contains 0 items. I've tried various formats for the javascipt lineItems parameter but still 0 items. I'm also open to some other way of getting these values in like the jquery form serialze method or something else.
I have a view which takes two objects: booking and list of reasons for canceling that booking.I have two classes: clsBooking, clsBookingCancelationReason I can read both objects in my view - no problems there. After I read the objects, I display the booking details and I generate a list of cancelation reasons in the following way:
[Code]....
The code above generates a list of cancelation reasons.How do I pick up the selected ReasonId from the list?
I need to generate a link that will contain the bookingId and the selected reason for canceling the booking.I can get the bookingId out easily since it's stored in the Model...but how do I go about the selected ReasonId?
I'm trying to pass a list of items from a LINQ query to a View, but I'm having trouble figuring out how to resolve a type issue. Here's the error:
The model item passed into the dictionary is of type 'System.Data.Linq.DataQuery`1[Project.Models.Diagnostic]' but this dictionary requires a model item of type 'Project.Models.Diagnostic'.
The issue seems to originate with this code from my Controller:
[Code]....
I tried changing the IQueryable<Diagnostic> to var and got the same error. Also played around with something like:
[Code]....
But then VS2008 says that diagnostics could never be null, and that's may not the best (or even valid) way to do it.

I have setup an httppost that sends a string into my controller, searches for some results using linq, and then sends the results to a view. In debug stepping through the code I can see the data that I am looking for being passed into the return view statement, but the page just appears to refresh (it doesn't render the view as expected with the result). why my controller fails to redender the view? (note: I didn't include the view because I can send a ToList() to it without an issue. For example, return View(_entities.Persons.ToList());
[HttpPost]
public ActionResult RenderSearch(string usersearchtext)
{
if (usersearchtext != null)
{
var search_results = from s in _entities.Persons
where s.Description.Contains(usersearchtext)
select s;
return View("SearchResult", search_results.ToList());
}
else
{
throw new NotImplementedException();
}
}
I have a dictionary I'm passing to a View. I want to be able to pass the values of that dictionary back to a Controller action from this same View. Is there anyway this can be accomplished without using a form? The situation is that I need to be able to pass these back to a controller action that is called when a user clicks an ActionLink from the View, and in my experience an ActionLink cannot be used to submit a values of a form, i.e. I've only been able to submit values of a form using the form's submit button. Unless there's a way to use an ActionLink to submit values in a form.Controller Action passes Dictionary to Controller in ViewData:
public ActionResult ModifyNewCrossListing(FormCollection form)
{
Dictionary<int, string> prefixlist = new Dictionary<int, String>();

View 4 RepliesI have following situation - I am pasing user info object from Controller to View. It contains GUID UserID, which i dont want to be seen on page. So I removed every Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc... from generated View source. And because of this when Html.BeginForm() returns that object back to Controller all values is there but UserID is lost??
If I leave Html.LabelFor(model => model.UserID), Html.TextBoxFor(model => model.UserID) etc.. in View everything is fine. But I dont want to show UserID? Where is the problem here?
<%= Html.LabelFor(model => model.C__User_Id) %>

I'm having problems passing values from the controller to the view. I created a boolean variable to use as a flag and want the view to render some html based on whether its true or false.
Unfortunately ViewData doesn't look like it can pass boolean values. I should be able to pass any datatype to a view (string, int, bool, etc...)

I have the following to get the Json abject passed from the controller and populate the various textboxes in the view. However, nothing is happening even though controller is passing a valid Json object. What is wrong with this code?
<script language="javascript" type="text/javascript">
$(document).ready(function() {
var url = '<%=Url.Action("DropDownChange") %>';
$("#vendorID").change(function() {
var selectedID = $(this).val();
if (selectedID != "New Vendor Id") {
//$.post('Url.Action("DropDownChange","Refunds")', function(result) {
$.post(url, { dropdownValue: selectedID }, function(result) {
alert(selectedID);
$("#name").val(result.Name);
$("#city").val(result.City);
$("#contact").val(result.Contact);
$("#address2").val(result.Address2);
$("#address1").val(result.Address1);
$("#state").val(result.State);
$("#zip").val(result.Zip);
});
}
});
});
This is the code in my controller;
public JsonResult DropDownChange(string dropdownValue)
// This action method gets called via an ajax request
{
if (dropdownValue != null && Request.IsAjaxRequest() == true)
{
paymentApplicationRefund =
cPaymentRepository.PayableEntity(dropdownValue);
paymentApplicationRefund.Address1.Trim();
paymentApplicationRefund.Address2.Trim();
paymentApplicationRefund.Name.Trim();
paymentApplicationRefund.City.Trim();
paymentApplicationRefund.Contact.Trim();
paymentApplicationRefund.State.Trim();
paymentApplicationRefund.Zip.Trim();
return Json(paymentApplicationRefund,"application/json");
}
else
{
return null;
}

I have a simple model where a Person has Gifts. I have a view which is a list of Gifts belonging to one Person.
My problem is with the Create action for a new Gift. I want it to default to the PersonID that we are already viewing the list of Gifts for. I tried simply passing the last PersonID (they are all the same)
Html.ActionLink("Create New", "Create", new { id = Model.Last().PersonID }) which works fine if there is already at least one Gift for that person but if this is the first Gift I don't have a value.
My Gift List controller knows the PersonID I want to pass but the view doesn't.
How do I pass this PersonID from my Gift List controller to my Gift Create controller via the Gift List view? Or is there a better way to do this?
I have and Article object that I update in my controller.... the object is passed into the controller and then I just call UpdateModel(inArticle) and it was all good. I now expanded my article to belong to a category and want to do that update there as well. I am not sure if it was the right thing to do but just as a start i hard-coded an update to the ArticleCategory table, just after I do the UpdateModel. This works but I am not sure how to code this update?
I am using the repository patter and i somehow feel that I should be passing an Article and an ArticleCategory object from the view to the controller? While I was writing this I thought that I could just extend my article object to include the categoryID but what if I really wanted to pass two un-related objects from the view to the controller? The UpdateModel persistes the database objects as by VoodooMagic, how would it work if I wanted to update 2 un-related objects?
I have this snippet in my html... Fusion Charts requires I feed it an XML to create a graph
<script type="text/javascript">
var myChart = new FusionCharts("/Content/Fusion_Charts/Charts/Column3D.swf", "myChartId", "470", "350", "0", "0");
myChart.setDataURL("/XML/Graph/?list=<%=Model.list%>");
myChart.render("Graph");
</script>
So in my XMLController I simply have a method like this
public ActionResult Graph(FusionChartsList list)
{
return View(list);
}
So my question is... how can I get the object to actually populate when passing it as url parameter??
How to use $.ajax(..) JSON to invoke asmx webmethods that have 'by ref arguments' for custom classes/objects? Is it possible?
My c# code -
public class MyCustomClass{ public int MyProperty; MyCustomClass(){}}
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public Method1(ref MyCustomClass MyCustomObj)

This all works fine if the webmethod's argument is NOT by ref.With the above mentioned signature of the webmethod, i.e. with a by ref argument, I get a server error (in server response seen using firebub ) -
I have an Edit form that utilizes the following ViewModel:
[Code]....
SUserDetail, User and CUDetail are LINQtoSQL classes in my [ .dbml ]. What the above ViewModel allows me to do, is provide a nice and neat Edit form populated with data from the above 3 objects.
However I am stuck on how to handle the HTTP Post for the Edit Action.
I'm playing around with a asp.net page that's using the IScriptControl interface to pass data from the code-behind to the custom javascript object running on the browser.I'm passing a number of properties via IScriptControl.GetScriptDescriptors(), and they're all working fine, except for one.That one is a class derived from System.Collections.Generic.Dictionary<>. And even that one has been working for me, so long as the elements in the collection were scalars - ints, doubles, and strings. But when I tried to pass a member of a class, it showed up as a null object in the javascript. The class in question is marked [Serializable]. I changed it to a struct, and got the same behavior.It looks as if the serializer used in IScriptControl does a shallow copy.
View 2 RepliesI have an application that uses DataContracts/DataMembers and Serialization to store information entered in a tab control. There are 8 tabs in the control (therefore 8 aspx pages). The final tab is used to write the information to disk.I am trying to understand: When should serialization be used in a web app? The objects are stored in memory not on disk. Is this another means of passing objects between aspx pages? If so when should serialization be used vs. session objects? How long is the serialized object retained in memory?Can I get a simple example of how to serialize in one page and deserialize the object in another page?I've read many blogs regarding serialization but have yet to find a simple example and none of them explain when serialization should be used vs. session objects?
